Had Brock been able, after the capture of Detroit, to lead his little army into Ohio, he might have cleared not only the Maumee River, but the whole western end of Lake Erie from American possession. Recalled in haste to defend Niagara, Brock left only two or three companies of troops as garrison at Detroit and Malden. The Indians could do little without the aid of regular forces, but they tried to carry both Fort Wayne and Fort Harrison by stratagem. The attacks were made almost simultaneously a few days after September 1, and not without skill. In the case of Fort Harrison the Indians were nearly successful, not so much in fighting as in burning it. With great difficulty its young captain, Zachary Taylor, of the Seventh Infantry, succeeded in saving his post. Fort Wayne was held by Captain James Rhea of the First Infantry until reinforcements arrived, September 12. Except the usual massacres of scattered families, the Indians accomplished nothing. Upon the State of Ohio, with its quarter of a million inhabitants, and of Kentucky with four hundred thousand, fell the immediate burden of defending the border between the Ohio and the Lakes. Governor William Henry Harrison of the Indiana Territory leaving Vincennes June 19, the day after the declaration of war, was at Cincinnati when threatening news began to arrive from Detroit. Harrison had military knowledge and instincts. He saw that after the capture of Mackinaw Detroit must fall, and that Hull could save himself only by evacuating it.[44] Harrison’s ambition, which had drawn him to Tippecanoe, drew him also to lead the new crusade for the relief or recovery of Detroit. He went to Kentucky at the invitation of Governor Scott, and under the patronage of Scott and Henry Clay he took the direction of military affairs. August 24 news reached Kentucky that Hull was shut in Detroit, and must surrender unless immediately relieved.[45] The Governor of Kentucky at once summoned what was then called a _caucus_, composed of himself, his successor elect Governor Shelby, Henry Clay, Justice Todd of the United States Supreme Court, Major-General Hopkins of the Kentucky militia, various Congressmen, judges, and other citizens,[46] whose whole authority was needed to warrant giving to Harrison, who was not a citizen of Kentucky, the commission of major-general and the command of the expedition to Detroit. By general acclamation, and on the warm assurances of universal popular approval, the measure was taken; and Harrison started at once for Cincinnati and Detroit to organize the campaign. The news of Hull’s surrender met him as he left Frankfort.
